How Skin Ages — A Layered Framework
Skin aging is not linear. From 25–30, epidermal turnover slows — dead cells aren't shed as quickly, the complexion dulls. From 30–35, dermal collagen production drops ~1% per year; expression lines emerge around eyes and forehead. From 35–40, hyaluronic acid loss accelerates; skin loses hydration and plumpness. After 40, the SMAS (deep facial support layer) and fat compartments descend — now the problem is architecture, not just skin.
This layered framework explains why one treatment is never enough. Epidermis needs chemical peels, microneedling or superficial laser; dermal collagen needs fractional RF, micro-focused ultrasound or RF microneedling; HA loss needs fillers and mesotherapy; SMAS descent needs HIFU or focused RF; expression lines need Botox. How much energy each layer receives is decided when we examine your skin.
